High Density Image Matching II
Innovations in matching algorithms as well as the increasing quality of digital airborne cameras considerably improved the quality of topographic data generated automatically from aerial images. This development motivated the launch of the joint ISPRS/EuroSDR project “Benchmark on High Density Aerial Image Matching” aiming at evaluating the potential of photogrammetric 3D data capture in view of the ongoing developments of software for automatic image matching. Basic scope is the evaluation of 3D point clouds and DSM produced from aerial images with different software systems. Such a comparative evaluation provides a platform for developers to demonstrate the state-of-the-art of their ongoing developments. Furthermore, it can help potential users like National Mapping and Cadastral agencies (NMCAs), which consider a state-wide-generation of high quality DSMs to understand the applicability of such tools while triggering further developments based on their needs.
As a joint test data set subsets of three aerial image blocks are provided. Two data sets cover nadir imagery, which are captured at different landuse and block geometry, while the third data set includes oblique aerial images.
